What a difference August makes. A few weeks ago, the Miami Dolphins faithful were giddy to see their haul of free agents in action. However, a fumbled handoff on their first preseason offensive snap portended a team which may not add up to the sum of its parts. Meanwhile, the Cleveland Browns seemed to be in full rebuilding mode, with a new coaching staff and a sophomore quarterback left for dead. But a few impressive performances by Brandon Weeden has everyone wondering if there’s a sleeper playoff contender in Ohio.

Neither of these conclusions are wise, of course. You just need to look at the Atlanta Falcons’ 1-3 record, or Sam Bradford’s 116.3 quarterback rating in the 2012 preseason to know that it’s foolish to read too much into August football. What we do know is that both these teams are hoping their sophomore quarterbacks can lead them out of the NFL desert. Will Miami’s new pieces fit together to lead them to the playoffs, or will they be just the latest team whose desperate GM dragged them into salary cap doom? Will Cleveland’s injection of young talent blossom, or will they play down to their inexperience? Here are three matchups that could decide which of these two teams starts the 2013 season on the right foot.

Across from Schwartz will be the incomparable Cameron Wake, the best 4-3 defensive end in the league last season. With 86 QB pressures in 2012, he tied Von Miller for the most in the NFL. He regularly schooled even the league’s best tackles, notching six pressures against Sebastian Vollmer in Week 13 and adding two sacks off Anthony Davis the next week. Schwartz’s weakness last season came on his outside pass blocking, where he allowed 61% of his pressures. Wake in turn is one of the most devastating outside rushers in the league, converting 49% of his outside pressures last season into sacks. And as good as Weeden looked this preseason, he still had a 39.6 passer rating when pressured. If Schwartz isn’t up to the task, Wake could single-handedly deflate Cleveland’s air attack.

Our LB's being able to cover the TE. Yeah its just a rookie TE but we saw what a good rookie TE can do to defenses last night in Denver. It opens up the entire passing game. If Wheeler and Misi are not up to the task, Miami will struggle. Wake is a force, but I fully expect a TE or back to chip him on every play so pressure will need to come from the other side as well. Slowing Richardson is key to forcing them into 3rd and longs. I think this game is going to be back and forth. Mistakes by Miami will be amplified by the buzz of opening weekend.
